Hello everyone,I have run into an interesting problem uninstalling exchange. And i was hoping someone could give me some help.I decided to remove Exchange from my test environment and start fresh. (one thing to add, exchange is connected to an "in production" active directory - so i cant afford to mess that up).First i have 3 servers. Edge, Hub, and the main exchange server role that holds the mailbox role on it.I uninstalled the hub server, and added that server onto my main exchange box. This was done for simplicity and take out a peice so i could troubleshoot a little easier. After doing that i went Uninstalled the edge server role from the edge box. After that i was trying to uninstall the main exchange server role. When trying to uninstall i got the following errors:___________________________________________Summary: 4 item(s). 1 succeeded, 3 failed.

There are no network issues that i can see considering i can ping my server from the inside and outside our network. And i can also ping other computers from this exchange server. I also looked at active directory and made sure i had permissions that allowed me full access (which i do). I am not sure where i went wrong and what i need to do to fix this... I cant uninstall exchange due to this.I know i also need to remove some storage groups before uninstalling but i doubt that would cause the registry/permissions error.Thanks in advance for you help!-M
